Symptoms:∙Had a "tearing sensation" followed by a "warming sensation" in the lateral lower abdomen while trying to have a bowl movement∙Dull sensation (uncomfortable) left oblique, feels like it is around the transversus abdominus muscle (in depth) down to where it nearly meets the pectinius muscle∙Dull sensation (uncomfortable) on the exterior lowest left rib (May not be related)∙Stool is firm yet unformed (not a full healthy stool sample) comes out in bits instead of a single log.∙Gas is a regular occurrence

From your description of the onset, it does sound as though there's at least a good chance that something herniated. A colonoscopy might be helpful, but a barium enema or even a CT scan with contrast may do the trick. If there's no herniation evident then a colonoscopy would be more likely to be required to rule out some other problem in the colon.

I hope this is helpful. Best of luck to you. Please follow up with us as needed.
